Nähstube: Simulating Cloth

In a Collaborative Augmented Environment

A cooperation of

University of Tübingen

and

Vienna University of Technology


   Project duration: 1998-

Description

Generating realistic images of cloth with different fabrics such as wool, cotton or silk is still a problem in garment design. The correct fall of a towel or a skirt can only be observed when the material is produced, the garment sewn and the result worn by a person. To reduce the design cycle we want to simulate this whole process with computer graphics.

We use our augmented environment "Studierstube" to interactively place and connect pieces of cloth over a tailor´s dummy. Complex 3D-placement operations like this are only difficult to achieve in desktop environments but are easily performed in an environment where 6 degrees-of-freedom input devices and 3D head-tracked viewpoints are implemented.

We use particle systems to simulate the fall of the cloth and obtain realistic draping behaviors. Our approach is more general than others and produces images much faster than other implementations.


Interaction in Studierstube

This sequence shows how the front portion of a knitted sweater is selected on the Personal Interaction Panel (PIP) and then positioned correctly on the tailor´s dummy.
The video stream has been captured directly from the head-mounted display, demonstrating rapid changes of viewpoint when the user moves his head.
